PEA-HULLER.

Specification of Letters Patent.

Original application filed February 9, 1916, Serial No. 77,183. Divided and this application filed April 17, 1918. Serial No. 228,990.

17 0 all whom it may concern:

Be it known that I, JOHN M. SANDERS, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Pea-Hullers, of which the following is a specification.

My invention relates to hullers for peas, beans and the like, and it consists in the combinations, constructions and arrangements herein described and claimed.

The present application is adivision of my prior application Serial No. 77,183, filed February 9, 1916. In the prior application aforesaid, the claims were drawn to a huller having means for separating the hulls from the peas or beans in which pneumatic means were made use of in this separation and in which means were provided for preventing the ejection of the peas or beans with the hulls. i

The main feature of the present application lies in the provision of a perforated plate for separating the peas or beans from the chaff which remain from the initial separation by the pneumatic means aforesaid, and in the provision of a device for keeping the perforated plate from clog-.

ging u A further object of the present invention is to provide a pea or bean huller having a perforated plate which is raked constantly from end to end in one direction by means of rakes or drags having teeth spaced apart so as to permit the peas or beans to be passed by the teeth while the chaff is carried'along by the teeth and eventually ejected by the machine.

In the present application I have disclosed substantially the same apparatus as that disclosed in the prior application aforesaid, since such disclosure is necessary for a clear understanding of the mechanism which forms the novel feature of the pres ent invention.

My invention is illustrated in the accompanying drawings which form part of this application and in which:

Figure 1 is a side elevation of one side of the machine.

Fig. 2 is a vertical longitudinal section through the device.

In carrying out my invention, I provide a casing 1 which maybe of any suitable form and material.

In the upper portion of the said casing a hopper 2 is provided, the said hopper being connected by a throat 3 with the interior of a toothed concave 4, in which is disposed a. toothedcylinder 5. The teeth of the concave and cylinder are spaced in such manner as to shell the peas or beans without splitting, cracking or otherwise injuring the same. a

I From the lower portion of the concave l the peas or beans and their hulls pass through a depending conduit 6 to the bottom of a discharge spout 7 for hulls; the said spout being carried through the rear end of the casing and being provided at its rear end with an upwardly extending transverse flange or other abutment 8, and being also. provided beyond the casing with an upper wall 9 that terminates in a depending transverse flange or other abutment 10. The spout 7 is for the discharge of the bulk or major portion of the hulls under the action of a blast of air from a rotary fan 11, and the abutment'or flange 8 serves to prevent any peas or beans that may be moved up the spout 7 from being driven out of the machine. Manifestly the hulls and chaff will be blown over the flange 8' but the peas or beans will bring .up against and be turned backby the flange, and will then gravitate through the spout to the lower end of the bottom thereof. The upper abutment or flange 10 serves to arrest and turn back any peas or beans that may ride upwardly on the hulls, and this without interfering with the free escape of the hulls and chaff between the two flanges 8 and 10.

The fan 11 is disposed in a casing 12, and from said casing a trunk 13 extends rearwardly to a point in front of the throat 6 and above the lower forward end of the bottom of the spout 7.

From the lower forward end of the bottom of spout 7 the peas or beans and portions of the hulls, chaff and other refuse, pass by gravity through an opening 14 and in rear of a curvilinear wall 15 and are deposited on a foraminous plate 16. This plate is capable of being withdrawn from the casing; the scheme being to use one plate when peas, particularly cow peas, are to be hulled, and a plate having larger apertures when beans such as velvet beans are to be shelled. The peas or beans, as the case may be, drop through the apertures of the plate 16 in company with a portion of the hulls and chaff, and tall upon an imperfora-te inclined support 17 by which the peas or beans alone are conducted to a boX or other receptacle, placed at the point indicated by 18in Fig. 2. A discharge opening 18?; for hulls and other refuse is provided between'the rear ends of the plate 16 and support 17, and a casing 19 ton ni eta n 20 s ceneecte threr a trunk with the forwa rd end of the Space b tw en the P ate 6 n s pport 7, this in order to assure all of the smallpor tions f th h ch nd. othe retu e being separated from the peas or beans, precedent to the delivery of the latter to the be}; 18.

It is important that the apertures 01? the,

plate 16 be kept clear during the operation of the machine so as to enable the'peas or beans to passthrough said apertures to the. ppor 7- I t r ore Provi e abore he plate 16 an endless drag 22. The said drag. 22 comprises sprocket or other suitable belts 23 and spaced transverse bars 24 on which are steel teeth or spikes 25. The lower stretch of the drag is opposed to and parallel,- with the upper side of the foraminous plate 16, and the teeth or spikes 25 are disposed, at approximate right angles to, the plate, and hence in its rearward traverse the, lower stretch of the drag will operate to. carry such hulls, chafi' and other refuse as find their way to, the plate 16, out of the machine, thereby maintaining the plate 16 in a clear statefor' the, passage ofi peas or beans, obviating-choking or clogging of the. machine, and materially promoting the efficiency of the machine as a whole.

It will be observed that the drag 22 traverses the entire, length of the perforated plate 16 from the lower to the upper end ina direction parallel to the plate. This is a prime importance because it is only by this means that the perforations in the plate 16 may be kept clear.

Having described my invention, what I claim and desire to secure by Letters Patent, is z In a huller, a casing having an opening termed. "in one end thereof, a removable foraminous plate arranged within the casing and inclined and extending i lpwardly toward and through said opening, an endless drag arranged within the casing near and above the foraminous plate and having a lower turn arranged parallelfwith the fpraminous plate and extending throughout the entire length of said foraminous plate, teeth earried byfthe endless drag and dispos dat ubst nt ll a r ht ng e w t elati n eret and a pted o emo aterial frem the openings in the foraminous p ate an t prepe m te e ng tu al y of sai f ram nj us p at a Cu ed Plate rmnged at the oiz r e d of he i r m ho plate to conduct beans and hulls to the lower end of the foraminous plate and beneath he e dless drag, an mpe ta Pl arranged near and beneath the foraminous plateand inclined; in the, same direction and provided at its opposite ends with outlet openings, and a blower having an outlet trunk arranged tov supply air into the space between the imperforate plate and the foraminous plate, at a point above the outlet opening at the lower end oft-he imperforate plate, the. Outlet trunk having its upper side wall arranged flush with and; in end-to-end relation to, the foraminous, plate.

In testimony whereof I atfin my signature in presence of. two witnesses,
